Which sampling techniques exist within probability sampling?

  • (simple) random sampling
    • each member of population has equal probability of being selected
    • use of random numbers applied to a list of entire population
    • purely random sample hard to achieve
  • stratified sampling
    • whole population is segmented into mutually exclusive subgroups and then units are randomly selected from each subgroup
  • cluster sampling
    • sample is selected in two or more hierarchical stages, with different units being selected at each stage
